.1i.@theivnoiielrfeatures of s t'niictuize andrarparts will appear froingthe rangement of following description.

In the accompanying drawings, which are merely intended to illustrate a practical embodiment of my invention and not to limit the scope of the same to the construction shown, Figure l is a side elevation of the` outer box or container with the trap members indicated in dotted lines; Fig. 2 is a side view of the trap frame and traps with tlie'box in section to show its interior; Fig. 3 is a vertical cross section taken along the line III-III in Fig. 2; Fig. t is a ViewV similar to Fig. 2, but showing the lid removed from the box and the trap frame moved outwardly to position the relief trap in the sewer line, and Fig. 5 is an end View 'of the trap frame showing the gasket or packing.

The following is a detailed description of the embodiment of my invention shown in the drawings.

A represents a box or outer container made oi metal or any other suitable material. l is a removable'wall, such as a top lid, of the box. 2 is an inlet connection and 3 an outlet connection bymeans otwhich the box may be connected up with the sewer. Tomaintain the usual drop in the sewer, it will be noticed that said connections are inclined and alined together.

B is -a frame or support which makes a. sliding tit in the box and may be raised or lowered as by means of a handle 4. C and D represent a pair of curved trap members having at their ends circumferential lips or flanges 5 which tit in seats or holes 6, in the end walls of the frame B. The two traps C and` D are so positioned in the frame B, that when the frame is in its innermost position, as shown in Figs. l and 2, Vthe upper or outer trap C registers with the inlet 2 rand the vent pipe ,Inca-ch or" said panels I mount a age between the.trapanchthesewerends, and

Said gasket is provided with ports 9 which register with the ends of the traps and are of the same diameter as said traps. Thus when the frame is in position,the gasket is compressed against the outer faces of the end anges of the trap members to prevent lateral escape Y of liquid or gas, but they do not in any way interfere with the passage of material through the trap. The edges of" .the gasket 8 are preferably beveled, as shown in Fig. 2, to prevent the edge of the gasket catching on the box wall when the frame is being moved.

Each trap may be provided with the usual vent pipe 10 which may connect with a common vent pipe 1l, which latter may extend up through a hole in the lid l.

In normal use the frame B is positioned so that the upper or outer trap C registers with the sewer inlet and outlet, but when the trap 4becomes clogged, the pipe 1l is disconnected, the lid l removed, and by means of the handle 4: the frame B is drawn into the position shown in Fig.- 4, thus positioning the un.

clogged trap D between the inlet 2 and the outlet 3, thereby enabling the material dammed up in the sewer to empty out. Then the frame B may be withdrawn completely from the box so that the trap C may be opened up and cleaned. The frame is then reinserted with the box and positioned once more'as shown in Figs. l and 2, ready for normal service. The lid is then replaced ll connected up.

' for cleaning or other purposes.

adapted to For the sake of illustration, I have shown the trap members removable vertically but it is evident that they may be slid into the outer box horizontally or otherwise, where, as when placed under a closet bowl, it would be inconvenient to arrange them for vertical movement.

It is also evident that when the traps are removed, the open box provides a convenient means of access to the interior of the sewer f What I desire to claim is -y 1. A trap mechanism adapted to be interposed between the abutting ends of a sewer orother passage and comprising a pair of trap pipes mounted to move in unison and be brought in turn into regissaid ends, for the purpose detration with scribed.

2. A trap mechanism adapted to be interposed between the abutting ends of a sewer or other passage and comprising a support Copies of this;v patent may be obtained for movable transversely between said ends, and a pair oftrap pipes mounted in said s upport and adapted to be brought in turn into registration with said ends, for the purpose i described.

be brought in turn into registration with' the movement of said support,

said ports by described.
